3 Claims.

My invention relates to bag frame structures in combination withfastening means for the same and has for its object to provide afastening means of simple construction carried by the bag frames in sucha way that it will not interfere with the means for attaching the handbag fabric to the frames.

In the drawing, which illustrates a preferred embodiment of myinvention:

Fig. 1 is an elevational view of a bag frame structure andfasteningmeans for the same;

Fig. 2 is an enlarged top plan View of the fastening means shown in Fig.1 with the frames in open position;

Fig. 3 is an enlarged rear view of my improved main fastener memberattached to one of the frame members;

Fig. 4 is a bottom view of the fastener installation shown in Fig. 3;

Fig. 5 is a fragmentary front view of the installation shown in Fig. 3;

Fig. 6 is an enlarged section taken on the line 66 of Fig. 1; and

Fig. 7 is an enlarged section taken on the line 1-1 of Fig. 1.

Referring to the drawing, I have shown in Fig. 1 a pair of frame membersI and 2 secured together at their free ends by rivets 3 or any othersuitable fastening means which will permit the members to be hingedtogether for relative swinging movement of one to the other. The framemembers I and 2 with which my improved separable fastener means is usedare .of the U-shaped cross-section type, as best illustrated in Figs. 6and 7, having an outer wall 4, an inner wall 5,

V and a base portion 6 connecting the two walls.

The walls 4 and 5 are spaced apart to form an outwardly opening channel(Figs. 6 and 7). The inner wall 5 has a flange I integral therewith andextending in substantially right angular relationship to the inner Wall.In my preferred form, as illustrated in Figs. 6 and 7, the outer wall 4is bent away from the inner wall 5 so that the bag material (not shown)may be brought over the outer wall 4 of each frame member and clenchedin the channel between the inner and outer walls by a subsequent bendingof the outer wall toward the inner wall.

The frame members I and 2 are held in locked position by a separablefastening means, as most clearly shown in Figs. 2 and 6, comprising amain fastener member 8 secured to the frame member I and any suitableinterengaging means carried by the frame member 2, such as theprojection 9, pressed from the material of the flange I.

Although I prefer to use my separable fastener means with frame membersof the type described, it should be understood that the fastening meansmay be used advantageously with frame members of other cross-sections.

Before the main fastening member 8 is secured,,a portion of the flange Iof the frame member I is cut away, as most clearly shown in Figs.

3 and 5, so as to leave an opening in the flange substantially in thecenter of the frame member. Next the material of the flange 1 adjacentto opposite ends of the opening is slotted as at I0 (Figs. 3 and 5)thereby forming lugs II for a purpose which will be hereinafter morefully described.

U-shaped cross-section in such a way that the foot portion I4 ispositioned at the bottom of the U-shaped cross-section (Fig. 6) insubstantially adjacent relation to the base portion 6, and theupwardly-extending portion I5 lies substantially adjacent to the innerwall 5 (Figs. 6 and 7) having portions at opposite ends disposed betweenthe flange I and the frame base portion 6 (Fig. 5). The foot portion I4is useful as an aid to maintaining the plate member in fixed positionwithin the cross-section, but I do not wish to be limited to the samebecause satisfactory attachment to the frame member has been providedwith this portion omitted. The portion I5 has a reduced neck portion I5extending through the opening in the flange I and joining the flangeportion I3 to the main body of the portion I5 (Fig. 5). The plate memberis held in secure attachment to the frame member by means of the lugs II which are bent to clamp the upwardlyextending portion I5 of the platemember firmly against the inner wall 5, as most clearly shown in Figs. 5and 7. After the plate member has been secured in final position theflange portion I3 overlies the outer edge of the wall 5 between the lugsII and extends from the portion I5 toward the frame member 2. The knobI2 is attached to the portion I3 in any suitable way such as by a nailor screw means I6 (Fig. 4) headed on the lower side of the portion I3and extending through apertures (not shown) in the portion I3 intoengagement with the material of the knob I2.

A fastener socket means I 1 (Figs. 2, 4 and 6) is provided, in mypreferred form, as an integral part of the flange I3 and adapted forcooperative fastening engagement with the projection 9. The socked meansI! is preferably formed by indenting the portion I 3 to form a recess ofbow-shaped crosssection, as best illustrated in Fig. 6. However, I donot wish to be held by the specific form of separable fastening meansillustrated and do,

scribed because it is apparent that there may be an interchanging of themeans relative to the parts with which they are associated or slightmodifications made in the form of the means- .the natural resiliency ofthe frame'members will permit the edge I8 to ride over the projection 9until the projection snaps into locking engagement with the recesssocket means II. The frame members may be readily separated by a slighttipping of the knob I2 to disengage the cooperating fastening means. 7

It is apparent that by my invention I have provided a separablefastening means which is adapted to operate entirely independently ofthe means for securing the bag material to the frame. Further-more, myfastening means is of relatively imple and inexpensive constructioncapable of easy assembly with the respective frame members with-which itis adapted to be used.

AlthoughI have illustrated and described a preferred embodiment of myinvention, I do not wish to be limited thereby because the scope of myinvention is best set forth in the following claims.

I claim:

1. A bag frame structure including a pair of frame members hingedtogether at their free ends, each of said frame members having an outerwall and an inner wall forming an outwardly opening channel whereby abag material may be secured in said channel between said outer and innerwalls, said inner walls each having a flange means extending outwardlyfrom the upper edge thereof, the flange means of the inner wall of oneof said frame members having an opening in one portion thereof, saidinner wall having at least one attaching lug integral therewith andextending into the channel of said frame member, and a fastening memberindependent of the securing means for the bag material, said fasteningmember having a plate portion clamped to said inner wall by means ofsaid attaching lug, said plate portion extending upwardly through theopening of said flange, and a flange portion integral with said plateportion and disposed above said inner wall, the said flange portionhaving an integral separable fastening means, and cooperating fasteningmeans carried by said other frame member.

2.
